My favorite real life story would probably be considered trolling because it involves RROD, so I will opt for my boring one. :P
Several months ago, I was talking with my Asian friend about the ps3, wii, pc, and 360(him being pc biased and me being ps3 biased) when another friend of ours who was 360 biased came to talk about games too. Instead of being kind towards his preferences, we began to bash the 360 and kinect for around 30 minutes(not even really arguing good points, mainly just calling it inaccurate and glitchy despite neither of us admitting to never playing it, but he did not know otherwise) until finally he switched the subject towards minecraft, at which point I felt alienated because I am the only one of them who has never played this supposed masterpiece. They then reconciled their differences by looking at each others similarities. I on the other decided to brag about the ps3's excellent upcoming 2011 lineup and continue to bash the opposing consoles. :P
Now that I think about it though, I rarely talk about video games to people I hang out with. Just not a thing most of my friends and I have in common lol.

Same here, with my friends, even though we have a BLAST playing Mario Kart and Brawl.

someone arguing that all video games are called "nintendo games". my position... no. games on the ps1 are not called nintendo games because they have nothing to do with nintendo. he was so adamant that i was wrong and refused to listen to reason. so i ended up "encouraging" him to listen to reason...

I never really got into a argument with no one mostly because everyone I usually hang out with are pro nintendo(Even my family members!) Though I did play around with someone who was pro Call of Duty and I said kirby was more manly then Call of Duty and I got a whole group involved and it was like 4 to 1. I laid down the facts and eventually won. It was funny but no one took it seriously. Its that around here people are more pro nintendo and I never hear stories like the ones I hear.

my friends thought i was an idiot when i was super excited to get wii sports and i kept saying nintendo should have just made the tagline for the game "better than real friends". haha they hated that and they would always try to put the wii down and i would always just say the wii is my real best friend, haha. which is pretty true though, if i had a 3ds now i wouldnt need to see anyone else ever again but im still stuck without one.

I got into an argument recently, on how third party publishers will always push more mass market appeal over core appeal, if given chances. Needless to say, EA and Bioware were a perfect example, the argument was on how Square Enix might potentially harm Eidos. It wasn't an argument in the sense he was clearly wrong (infact square enix effect on Eidos might never be measured). However he now fully agrees with me after seeing Hitman's new trailer. :P

Where I live, we have really shit taste in games IMO and almost no knowledge whatsoever of gaming. These are views/assumptions concerning gaming which are wipespread at my school/6th form college/local area. Obviously I contest every single one of these and have got into numerous arguments:

1. 'True' gaming didn't start until the launch of the PSX. Previous generations as well as the Saturn are not 'true' gaming consoles

2. A game's age rating helps determine it's quality, if a game has a PEGI rating of 16 or 18+ it is almost without certain a better game than if it was rated 3, 7 or to a lesser degree 12 +.

3. A game can only be described as 'hardcore' if it features all or many of the following: guns, bloody violence, half naked women, sex, drug use or swearing. The only exceptions to this rule are Gran Turismo and some sports games.

4. Linking with the previous point, the word 'hardcore' cannot be under any circumstances be extended to include any game on Nintendo platforms. 'Hardcore' is essentially a blanket term to describe 'not Nintendo'.

5. The only decent games that Japan produces are Gran Turismo, PES and Metal Gear Solid. Everything else is kiddy/shit/weird/borderline child pornography.

6. All games should appeal to the so called 'adult audience'. However a better description for this audience would be 'Western Teenage Male' as it is predominately FPS games and FIFA, as anyone over the age of 30 is not considered part of the 'adult audience'. Games like Brain Training, which saw most appeal from adults, are actually part of the kiddy/casual/Nintendo/weird Japanese shit mega-audience.

7. IGN are the only source of gaming news. There reviews are easily the most trustworthy, but despite this their reviews for any game one doesn't like are quite clearly 'biased'. Therefore, in gaming debates and arguments, IGN can only be used on the side advancing these points. A clear example is when someone claims to me that the Wii has no good games, and uses IGN to illustrate the quality of 360/PS3 games, I cannot counter by bringing up the score of certain Wii games (such as the 2 galaxies). In this situation, IGN are 'biased' in favour of the Wii and therefore cannot be used to defend my viewpoint.

8.  The only good graphical style in photorealism.  Any cell shading or anything deviating from photorealism automatically relegates a game's appeal strictly to 'babies only'.  Even the 2008 Prince of Persia (IMO the best PoP game), was automatically crap due to it's art style.  'Real men and gamers' only play games with a photorealistic art style.

9. 'Mature' games are the pinnacle of the gaming medium.  However, what determines a game as 'mature' is strictly limited to age rating.  You should've seen the shitstorm when I proposed that Final Fantasy Tactics was a far more 'mature' game than any CoD, due to its' story and in particular it's themes.

10. Graphics are one of if not the most important thing in a game.  The 360 is instantly superior to the likes of the DS, SNES and PSX due to it's graphical capabilities.  However, this logic cannot be used to imply that the PC and to a lesser degree PS3 is superior to the 360.

11. Nintendo has no new IPs.  Games like Wii Sports, Disaster DoC, Nintendogs, Brain Training, Steel Diver, etc do not count for some reason.  This is despite the likes of Red Dead Redemption and Guitar Hero being called New IPs.  When I ask for their reasoning, I get 'You know what I mean...'.  I actually don't understand what they mean.

That reminds me of a time when someone was desperately trying to convince me that Left 4 Dead was made by Apple, and that Valve was owned by Apple because it wasn't Microsoft.

I think I'd just laugh at people who debated these as both true. Well done for educating people.

My main arguement and I've had this a few times, is with a specific housemate about 360 and PS3, defending my choice in console. Annoyingly I hardly remember them as they are in conversasion and just silly so I don't remember but it's sad when i mention failure rates and in my specific house we've had 3 PS3 failures and no 360 failures, yet have 2 of each console. 

Another weird moment, and wasn't really an arguement. Is when I mentioned the Tokyo Game Show not long ago, 3 of my housemates who game on a regular basis had never heard of it. I found this strange but one said the he's not interested in it because it's Japanese and doesn't affect him. My explanations that without Japan we'd have no games industry like it is today was a bit lost on him, his favour game is Street Fighter 4.

*gasps* TAKE THAT BACK!!
